[Question 1: What does containment mean when it comes to outbreaks?]
2
17614
3592
[Qüestió 1: Què significa la contenció pel que fa als brots?]
00:21
Containment is this idea that you can focus your effort on control
3
21230
3613
És la idea que es poden focalitzar els esforços en controlar
00:24
very much on the cases and their contacts.
4
24867
2297
principalment els casos i contactes respectius,
00:27
So you're not causing disruption to the wider population,
5
27188
2699
de manera que no pertorbes el conjunt de la població.
00:29
you have a case that comes in, you isolate them,
6
29911
2685
Si apareix un cas nou, l'aïlles,
00:32
you work out who they've come into contact with,
7
32620
2303
investigues amb qui ha mantingut contacte,
00:34
who's potentially these opportunities for exposure
8
34947
3037
ja que és possible que altres hagin estat exposats.
00:38
and then you can follow up those people,
9
38008
2128
Després, els fas un seguiment.
00:40
maybe quarantine them, to make sure that no further transmission happens.
10
40160
3496
Posar-los en quarentena per assegurar que no es produeixin més contagis.
00:43
So it's a very focused, targeted method,
11
43680
2463
És un mètode molt focalitzat i específic,
00:46
and for SARS, it worked remarkably well.
12
46167
2600
i en el cas del SARS va funcionar molt i molt bé.
00:49
But I think for this infection,
13
49429
1848
Però per combatre aquesta infecció,
00:51
because some cases are going to be missed, or undetected,
14
51301
3524
com que molts casos ens passaran per alt o no seran detectats,
00:54
you've really got to be capturing a large chunk of people at risk.
15
54849
3143
és fonamental retenir una gran part de la població en risc.
00:58
If a few slip through the net,
16
58016
1492
Si se te'n colen alguns,
00:59
potentially, you're going to get an outbreak.
17
59532
2118
el més probable és que hi hagi un brot.
01:01
[Question 2: If containment isn't enough, what comes next?]
18
61674
3587
[Qüestió 2: Si la contenció és insuficient quin seria el següent pas?]
01:05
In that respect,
19
65285
1216
En aquest cas,
01:06
it would be about massive changes in our social interactions.
20
66525
3364
caldrien grans canvis en les nostres interaccions socials.
01:10
And so that would require,
21
70267
1722
Això requereix que,
01:12
of the opportunities that could spread the virus
22
72013
2294
respecte a les possibilitats de contagi del virus
01:14
so these kind of close contacts,
23
74331
2016
en els contactes pròxims,
01:16
everybody in the population, on average,
24
76371
2256
tots els grups de població,
01:18
will be needing to reduce those interactions
25
78651
2896
hauran de reduir aquestes interaccions, de mitjana,
01:21
potentially by two-thirds to bring it under control.
26
81571
2648
fins a dos terços per tal de tenir-ho sota control.
01:24
That might be through working from home,
27
84243
2735
Es pot aconseguir treballant des de casa,
01:27
from changing lifestyle
28
87002
1889
canviant l'estil de vida
01:28
and kind of where you go in crowded places and dinners.
29
88915
3434
i els llocs on vagis, llocs amb molta gent o sopars.
01:32
And of course, these measures, things like school closures,
30
92897
2779
I, és clar, mesures com el tancament de les escoles
01:35
and other things that just attempt to reduce
31
95700
2110
i altres amb l'objectiu de reduir
01:37
the social mixing of a population.
32
97834
1984
les trobades socials dels ciutadans.
01:39
[Question 3: What are the risks that we need people to think about?]
33
99842
4008
[Qüestió 3: En quins riscos cal que pensi la gent?]
01:43
It's not just whose hand you shake,
34
103874
1705
No és sols a qui estrenys la mà,
01:45
it's whose hand that person goes on to shake.
35
105603
2128
sinó a qui estreny la mà aquesta persona.
01:47
And I think we need to think about these second-degree steps,
36
107755
2928
Hem de reflexionar sobre aquestes accions de segon grau,
01:50
that you might think you have low risk
37
110707
1991
perquè potser penses que tens risc baix
01:52
and you're in a younger group,
38
112722
1763
i que pertanys a un grup més jove,
01:54
but you're often going to be a very short step away
39
114509
3125
però la realitat és que sovint et trobaràs a pocs passos
01:57
from someone who is going to get hit very hard by this.
40
117658
2661
d'algú que acabarà greument afectat.
02:00
And I think we really need to be socially minded
41
120343
2608
Hem de concienciar-nos socialment
02:02
and think this could be quite dramatic in terms of change of behavior,
42
122975
3308
i encara que suposa un canvi radical pel que fa al comportament social
02:06
but it needs to be
43
126307
1635
és necessari
02:07
to reduce the impact that we're potentially facing.
44
127966
2397
per a reduir l'impacte que segurament tindrà.
02:10
[Question 4: How far apart should people stay from each other?]
45
130387
3736
[Qüestió 4: A quina distància hem de mantenir-nos dels l'altres?]
02:14
I think it's hard to pin down exactly,
46
134147
1889
És difícil d'establir exactament,
però el que hem de pensar és que no s'ha demostrat
02:16
but I think one thing to bear in mind is that there's not so much evidence
47
136060
3516
que sigui com un aerosol que arriba molt lluny:
02:19
that this is a kind of aerosol and it goes really far --
48
139600
2659
abasta distàncies curtes.
02:22
it's reasonably short distances.
49
142283
1548
02:23
I don't think it's the case
50
143855
1302
No crec que ocorri que
02:25
that you're sitting a few meters away from someone
51
145181
3214
si estàs assegut a uns metres d'algú
02:28
and the virus is somehow going to get across.
52
148419
2161
el virus arribi fins a tu.
02:31
It's in closer interactions,
53
151224
1354
Són interaccions pròximes,
02:32
and it's why we're seeing so many transmission events
54
152602
2932
per això estem veient com molts contagis
02:35
occur in things like meals and really tight-knit groups.
55
155558
3854
es produeixen durant els àpats i a grups molt units.
02:39
Because if you imagine
56
159436
1317
Imagineu,
02:40
that's where you can get a virus out and onto surfaces
57
160777
3004
d'aquí és d'on pot sortir un virus i que es quedi a les superfícies,
02:43
and onto hands and onto faces,
58
163805
1638
a les mans i a la cara.
02:45
and it's really situations like that we've got to think more about.
59
165467
4021
Són el tipus de situacions sobre les que cal reflexionar més.
02:49
[Question 5: What kind of protective measures
60
169512
2151
[Qüestió 5: Quines mesures de protecció haurien d'implantar els països?]
02:51
should countries put in place?]
61
171687
2120
02:53
I think that's what people are trying to piece together,
62
173831
2625
És precisament el que intenten esbrinar,
02:56
first in terms of what works.
63
176480
1780
primerament en quant a què funciona.
02:58
It's only really in the last sort of few weeks
64
178562
3131
Durant les últimes setmanes
03:01
we've got a sense that this thing can be controllable
65
181717
2810
és quan hem pogut percebre que el virus es pot controlar
03:04
with this extent of interventions,
66
184551
1674
amb aquestes intervencions.
Però no tots el països poden fer el mateix que la Xina.
03:06
but of course, not all countries can do what China have done,
67
186249
2864
Algunes d'aquestes mesures
03:09
some of these measures
68
189137
1199
03:10
incur a huge social, economic, psychological burden
69
190360
3714
tenen un gran cost social, econòmic i psicològic
03:14
on populations.
70
194098
1255
per a la població.
I també hi ha una limitació temporal.
03:16
And of course, there's the time limit.
71
196173
1849
A la Xina els van confinar 6 setmanes.
03:18
In China, they've had them in for six weeks,
72
198046
2131
Mantenir això és complicat.
03:20
it's tough to maintain that,
73
200201
1376
Cal considerar solucions intermèdies
03:21
so we need to think of these tradeoffs
74
201601
1825
03:23
of all the things we can ask people to do,
75
203450
2572
de tot el que poguem demanar a la gent que faci,
03:26
what's going to have the most impact on actually reducing the burden.
76
206046
3515
les coses que tinguin major efecte en reduir la càrrega.
